When Miro’s data team pointed AI agents directly at its Snowflake environment, the agents got the wrong answer more than 65% of the time. The problem wasn’t the model — it was context. With more than 10,000 tables and no semantic layer to guide routing, the agents had no way to know which data assets matched which business questions.DataHub is releasing a context intelligence layer Thursday that mines existing SQL query history to build a semantic index — and exposes it to agents via MCP, LangChain, Google’s Agent Development Kit and CrewAI. The company calls it Context Intelligence, and it’s built on the same query-log infrastructure DataHub has used for lineage tracking in production deployments worldwide.The company was founded by the team that built DataHub as an open source project at LinkedIn, where co-founder and CTO Shirshanka Das led data infrastructure for nearly 11 years. The open source project now has more than 15,000 contributors and 3,000 production deployments worldwide."For the first time, enterprises can turn years of analyst query history into a living, retrievable knowledge base where agents stop hallucinating joins because they have access to the joins that have worked before, validated by the people who ran them," Shirshanka Das, co-founder and CTO of DataHub, told VentureBeat in an exclusive interview.Why query history beats raw schema for agent routingDataHub began as a metadata management project at LinkedIn, built to solve two problems simultaneously: making data easy to find and use across the organization while ensuring it was only used for the right reasons. Das open-sourced the project in early 2020 after nearly six years of internal development.The primary use case in the years since has been lineage — understanding how data flows from operational systems through streaming infrastructure into warehouses and out to business tools. Regulatory compliance audits, operational triage and new engineer onboarding all depend on that lineage graph. Postgres is the most-connected source in the DataHub deployment base globally, followed by MySQL, Oracle and the major cloud warehouses including Snowflake and Google BigQuery. The platform supports more than 100 connected metadata sources.That deployed base matters for what DataHub is releasing. The query log extraction and SQL parsing capabilities powering Context Intelligence were developed across years of production deployment, not built for this release. The same infrastructure now serves agents querying a semantic index at runtime."The consumption layer has changed from humans to agents," Das said.Context Intelligence mines validated query history, not raw logsContext Intelligence is a new capability layer built on top of DataHub's existing open source metadata foundation. The open source platform has spent years extracting and parsing query logs from connected warehouses for lineage tracking. That same infrastructure is what Context Intelligence draws on to build the semantic index. The capability is new. The underlying plumbing is not.Filtering for signal. Warehouse query logs contain too much noise to use directly. DataHub's engine filters for what Das describes as the "golden queries," meaning high-quality analyst queries and scheduled pipelines that represent proven business logic.Inverting SQL into semantic definitions. The engine extracts patterns from those queries and translates them into structured text definitions DataHub calls semantic anchors. Those anchors form the retrieval basis agents draw on before generating SQL.
